Answer:

45% decrease

Step-by-step explanation:

The formula for percent of decrease/ increase is

Original - change/ original

So 40 - 22 = 18

18/40 = 0.45

Turn 0.45 to percent by moving the decimal two spaces to the right

45%

You can check by multiplying the original number by the percentage. So,

40 x 0.45 = 18
